Abstract (en)

The method involves finding estimations of combinations of physical quantities of a model from data expressed in two time scales. An analysis of the estimations is carried out to determine a scale factor allowing establishment of a match between two time scales. A joint inversion procedure is performed, where scale factor allows expressing synthetic data associated with the model and evaluating difference between the two data.
